A warranty deed and a quit claim deed are both legal documents that can be used to transfer ownership of real property. Warranty deeds and quitclaim deeds are both deeds used to transfer ownership of property, but a warranty deed comes with certain legal guarantees.A warranty deed and a quitclaim deed are two different types of real estate deeds that individuals use in property transactions based on their legality. In Massachusetts, a quitclaim deed is akin to a special warranty deed elsewhere. The quitclaim deed is the most commonly used deed in the purchase and sale of residential property in Massachusetts. Quitclaim deeds in Massachusetts are similar to "special warranty deeds" in other states. Unlike a quitclaim deed, a warranty deed can grant a certain level of assurances when ownership is transferred. For home purchases, warranty deeds usually offer the highest level of protection for the buyer. A Warranty Deed gives more promises, meaning the person transferring the deed says there are no legal problems with the property's ownership. With a quitclaim deed, the grantor does not cover any preexisting encumbrances on the property, such as restrictions or easements.
